They will fit. I have been trying to come across one for 3 years or so. I checked into buying the hub only from Husky, but the assembly is NLA and one of the main parts (can't remember which one) was too.
On top of that there is a difference in spoke angle, between the cush and standard hub.

Edit, I'm not so sure the axle size is the same. I have converted standard pre 03 hubs by changing bearings seals and spacers.

I have had a fleabay search set up for many, many months and no hits. I checked with Halls. The '00-05 hub is available, but the cush rubbers are on backorder and the sprocket carrier is NLA. Would for sure be adaptable if you could find one, as some of the bearings are the same part number.

I called Haan in the Netherlands this morning, and they don't support the TE610 with a cush.
